Problems solved by technology
[0004] The above existing technical solutions have the following defects: the circuit board in the prior art is not pre-soaked, and the printed circuit board is directly brushed with a brush. When the flux or stain on the circuit board is combined with the circuit board When it is firm, it is often necessary to increase the strength to scrub the circuit board, which is easy to cause damage to the surface of the circuit board

The invention relates to a cleaning process and device for an anti-interference mixed-pressure circuit board, belonging to the technical field of circuit board cleaning, and its technical points include: putting the circuit board after welding into a first-level cleaning structure; Inject cleaning agent into the cleaning structure until the cleaning agent soaks the circuit board; set the soaking temperature, and start the first-level cleaning structure to heat the cleaning agent to the set temperature; soak the soldered circuit board; start the first-level cleaning structure to The final circuit board is vibrated and cleaned; the circuit board cleaned by the primary cleaning structure is moved into the secondary cleaning structure; pure water is injected into the secondary cleaning structure; Step 8: Start the secondary cleaning structure to perform secondary cleaning on the circuit board Cleaning; move the circuit boards cleaned by the secondary cleaning structure into the drying structure; start the drying structure to dry the circuit boards after the secondary cleaning. The present invention advantageously reduces the possibility of circuit boards being damaged during the cleaning process.
Description
technical field [0001] The invention relates to the technical field of circuit board cleaning, in particular to a cleaning process and a cleaning device for an anti-interference mixed-pressure circuit board. Background technique [0002] After the circuit board is soldered, flux, solder residue, oil stains, hand sweat, etc. will remain around the solder joints and on the surface of the printed circuit board. If the circuit board is not cleaned in time, the circuit board will suffer from solder joint corrosion and insulation resistance. Therefore, after the circuit board is soldered, it is necessary to clean the circuit board to improve the quality and service life of the product. [0003] The existing Chinese invention patent application with the patent publication number CN108990304A discloses a cleaning process for printed circuit boards, including: Step 1: placing the printed circuit boards in a cleaning bucket, which is provided with a water-based cleaning process. agen...
